Abstract: It is the key for realizing fast and extract flatness
control to establish mathematic model between shape error character
value and shape adjustments. The concept of transfer matrix and
mathematic model is proposed based on founded the idea of transfer
function and mathematic model. According to 900 mm HC 6-rolling as an
object, based on GA-BP network model , the transfer matrix for this
rolling mill has been founded and processed practical application,
obtained satisfied effect. It offers a novel theory and method for
flatness control and application.
Key words: Flatness control Transfer matrix GA-BP model
